Prepayment Purchase Order - 12.1.3

We have a requirement to prepare prepayment PO which should be match to invoice in AP.

Earlier we were using Non-PO invoice and used to create standard invoice while entering prepaid account at line distribution level. We were also using multi-period accounting concept to amortize prepaid expense every month automatically.

Now since we are implementing Purchasing module, we would like to route prepayment through purchasing and also want to use multi-period accounting concept in AP to automatically amortize prepaid expense every month.

I am doing following:

1. Create a PO and assign prepayment account as charge account

2. Create standard invoice AND match prepayment PO by using match action 'PO Match'
